PURPOSE: The paper intends to present the results of using new methods of a new generation diode laser transscleral cyclophotocoagulation (TSCPC) in patients with different types of glaucoma. PATIENTS, MATERIALS AND METHODS: There have been treated 53 eyes from 59 patients with glaucoma refractory to medical, laser or surgical treatment. We have used the newest generation of 810 nm wavelength diode laser. There have been used two protocols of continuous-wave diode laser emitting radiation for cyclophotocoagulation. The first technique - the standard cyclophotocoagulation (high power and low exposure duration) - has been used for the eyes with limited visual function [visual acuity (VA) extremely low or eyes disorganized]. The second technique - slow coagulation, also named "slow burn" (lower power and greater exposure duration) - has been used for the eyes with apparently better visual prognosis (VA≥20∕400). For evaluation, we followed both subjective parameters (eye pain decrease) and objective parameters [intraocular pressure (IOP) lowering and VA evolution]. Patients have been evaluated before laser intervention and postoperative at one, three and six months. RESULTS: IOP has significantly decreased in both patient groups. In the eyes with better visual function (VA≥1∕20), where we have used the "slow coagulation" technique, we found no decrease of VA. Eye pain has disappeared in almost all treated cases. CONCLUSIONS: The diode laser TSCPC is an efficient method of lowering IOP and decreasing eye pain. The "slow burn" technique has been shown its efficiency for extending the indications of cyclophotocoagulation also in glaucomatous eyes with better functional prognosis.
